JAVA-JDK with the environment, Eclipse tools know

First, the JDK with the environment;

1. JDK Mind Map

2. Test code:

Attention should be paid to the distinction between the case of the point class name, the symbol for the English input method,;.

Class Hello
{
public static void Main (String [] args)
{
System.out.println ("Java");
System.out.println ("Hello World");
System.out.println ("Hello World");
System.out.println ("# # # # #");
System.out.println ("# # #");
System.out.println ("# #");
System.out.println ("#");

}
}

Second, Eclipse tools

1. Mind Mapping

2. Initial knowledge of Eclipse training

For example: Use the * symbol everywhere name.

public class Hello {

public static void Main (string[] args)
{
TODO auto-generated method stubs
System.out.println ("*");
SYSTEM.OUT.PRINTLN ("* * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * * * *");
SYSTEM.OUT.PRINTLN (* * * * * * * * ******* *); //Auto-complete shortcut key alt+/
SYSTEM.OUT.PRINTLN ("* * * * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * ******** *");
SYSTEM.OUT.PRINTLN ("* * * * * * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * * * * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * * *");
SYSTEM.OUT.PRINTLN ("* * * * * * *");
SYSTEM.OUT.PRINTLN ("* * *");
}

}
